Abstract	Adventitious roots ofPanax ginseng C.A. Meyer (a natural tetraploid) were treated with 50 or 100 mg L$^{-1}$ colchicine for 12, 24,36, 48, or 60 h to induce polyploid (octoploid) roots. The largest number of octoploid roots was obtained with a 100 mg L$^{-1}$ colchicine treatment over 60 h. To verify that ginsenoside was being accumulated in the developing tissues, the tetraploid (control) and octoploid roots were cultured for 40 d in Murashige and Skoog media that lacked NH$_{4}$NO$_{3}$ but was supplemented with 2 mg L$^{-1}$ naphthaleneacetic acid and 50 g L$_{-1}$ sucrose. Levels of fresh and dry biomass were greater in the octoploid roots. Although total ginsenoside and Rb-group ginsenoside contents were less in the octoploid roots than in the tetraploids, the former had a higher amount of Rg-group ginsenosides (especially Rg1). These results demonstrate the benefit that polyploid adventitious roots provide in enhancing the production of secondary metabolites in ginseng.
